    Areas affected...parts of the Florida Panhandle

    Concerning...Tornado Watch 103...

    Valid 102335Z - 110130Z

    The severe weather threat for Tornado Watch 103 continues.

    SUMMARY...The risk for severe weather has become increasingly
    negligible, at least in the near term, but could increase once again
    later this evening across at least coastal portions of the Florida
    Panhandle around Apalachicola. While the remainder of Tornado Watch
    103 may be allowed to expire at 9 PM EDT, trends will need to
    continue to be monitored for the possibility of a new severe weather
    watch later this evening.

    DISCUSSION...The initially strong and better organized cluster of
    storms has undergone considerable further weakening as it continues
    to progress through an environment characterized by stable
    near-surface lapse rates and less unstable low-level inflow across
    and inland of northeastern Gulf coastal areas. Outflow, trailing
    the forward propagating portion of the remnant convective system now progressing into the Apalachicola vicinity, has advanced 60-70 miles
    offshore of the western Florida Panhandle, but appears to have
    stalled in advance of a significant mid-level short wave still west
    of the lower Mississippi Valley.

    Renewed thunderstorm development is ongoing along and southwest of
    the stalling portion of the outflow, aided by forcing associated
    with strengthening low-level warm advection beneath increasingly
    difluent upper flow. It appears that this may increasingly acquire
    low-level inflow of moderately unstable air over the next few hours,
    with potential for further upscale growth and the evolution of
    another organizing convective convective cluster along the outflow
    boundary through mid/late evening. While the bulk of the strongest
    storms may remain offshore, it is possible that the risk for severe
    storms could increase again across coastal areas around Apalachicola
    later this evening.
